This is subjected to a blast treatment in which, for example, a zirconia ceramic granulate, pressure-atomized steel powder or a sintered hard metal spray granulate is dry-blasted against the surface to be treated. The measure leads to a surface smoothing and reduction of residual tensile stresses or generation of residual compressive stresses in the coating.

It has been found that, in particular, the layer sequence Al 2 O 3 -TiCN-TiCNO-TiAlCNO-Al 2 O 3 is expedient. A TiCN layer can be applied directly to the Al 2 O 3 layer.
